Fisher Pen Refills SPR4B 3-PACK

I saw someone else had this question, so I thought it might be helpful to mention that my 20 year old Sensa pen had its original Fisher refill, and when I looked up the model # SPR4B, this one was what I got and it fits and works PERFECTLY!

Works fine, dose its' job and they arrived on time.

Bought these for my space pen. Well made and long lasting. Still on the first refill and have used pen for over 1 year now with pen usage everyday.

Refills are great, able to use them in wider pens due to arthritis. Flow is perfect and the broad point gives a distinct line.

They work as advertised. I bought the bold version. It is not at all bold, however.

Fisher Space Pen.. It's a name I know & trust.I am quite happy with this purchase, and will purchase this (or similar) product again.

This was a three pack and only got one!

I use these refills in my Fisher Bullet space pen. They work great. I'm highly satisfied.
